Anton Geiser (surname also spelled Geisser; October 17, 1924 – December 26, 2012) was a Yugoslav-born member of the SS-Totenkopfverbände during World War II, who served as a guard at both the Sachsenhausen and Buchenwald concentration camps. In 1956 he moved to the United States, settling in Sharon, Pennsylvania, where he had family. In 1962 he became a naturalized American citizen. In 2006 he was stripped of his citizenship on the grounds that it would not have been granted had the full details of his role in the German military been known; in 2010 a US judge ordered him deported to Austria, the country from which he had immigrated. He died in Pittsburgh on December 21, 2012, while still battling his deportation. Background Geiser was born in the former Yugoslavia, in the village of Selci Đakovački (part of Đakovo) in eastern Croatia. In September 1942, shortly following the invasion of Yugoslavia by Nazi Germany, Geiser, an ethnic German, was drafted into the Waffen SS. He was 17 years old at the time. SS career Once in the SS, he was chosen to be a member of the SS-Totenkopfverbände, the so-called "Death's Head Battalion" that most concentration camp guards belonged to. He was sent to the Sachsenhausen concentration camp near Oranienburg for training, where he was told that as a matter of policy prisoners attempting escape were to be shot. While there, he served as a perimeter guard and escorted prisoners to and from labor sites. Later, he served at the Buchenwald concentration camp in a similar capacity, escorting prisoners to the Arolsen subcamp as necessary and finally aiding with the evacuation of Arolsen's prisoners back to Buchenwald when the subcamp was closed near the war's end. Life after World War II After World War II ended, Geiser lived in Germany for three years before moving to Austria in 1948 to be with his girlfriend, Theresia (1925-2011). He married Theresia in Austria before immigrating to the United States in 1956. After arriving in the United States, Geiser settled in Sharon, Pennsylvania, about 75 miles (120 km) northwest of Pittsburgh, and worked as a steel worker for Sharon Steel Corporation before retiring in 1987, raising three children in the process. He became naturalized as a United States citizen on March 27, 1962. Loss of US citizenship, deportation, and death By the late 1990s, Geiser was under investigation by the United States government's
